Infinera says that NBN Co, Australia’s wholesale open-access broadband provider completed a successful proof of concept of XR optics-based point-to-multipoint coherent optical technology. The trial demonstrated XR optics’ compatibility within the NBN Transit Network, a DWDM network spanning over 65,000 km across Australia.

The company says the trial highlighted the ability of XR optics to dramatically simplify transport network architecture while reducing CapEx and OpEx across diverse applications. Providing multiple 100Gbps of capacity subdivided into discrete subcarriers, XR optics enables dynamic capacity management and optical capacity optimisation. The demonstration was designed to inform how NBN Co considers options to evolve its transport network to support growing data demands in the future.

“The NBN Transit Network is our national backbone, supporting the growing data needs of Australians as they rely more on broadband for their work, education, social and entertainment needs. It is important that we keep track of new innovations to guide how we evolve our network to help meet changing needs in the future,” said Ray Owen, chief technology officer at NBN Co. “Working with Infinera helps us to understand the options and design our pathways accordingly.”

“This trial with NBN Co provides a proof point illustrating how Infinera’s digital subcarrier-powered XR optics can be seamlessly integrated into existing networks and successfully applied in a variety of network applications from backhaul networks to data centre interconnect,” said Dave Welch, Infinera chief innovation officer and co-founder. “The XR optics trials Infinera has conducted continue to represent a radical shift in the way future networks can be built, promising a dramatic reduction in TCO, helping to set a new benchmark in scalability, and increasing service flexibility and velocity.”

XR Optics, which won the ECOC 2020 Exhibition Industry Award for The Most Innovative Product was launched at ECOC 2019. The technology enables a single high-speed transceiver to simultaneously send and receive independent data streams to and from numerous low-speed transceivers. By leveraging these capabilities, Infinera says network operators will be positioned to significantly reduce the number of transceivers in the network, eliminate the need for costly intermediate aggregation devices and more efficiently optimise transport infrastructure for hub-and-spoke end-user traffic flows.
